Abstract

The invention relates to a method for automatically controlling the material feeding of stone breaker and relative controller, wherein said method comprises that: the three-phase power circuit of main motor and assist motor is connected to one electric appliance; at least one-phase power line of main motor is through the current inductor coil of over-current protective controller; three-phase power source of assist motor is connected to the closed touch point of alternative contactor of controller; the over-current protective controller comprises present current inducer rectifier circuit, control integrated circuit, direct-current power circuit and alternative contactor. The invention is characterized in that: it also comprises electric switch circuit used to adjust the start load of main motor. The invention connects controller to the power circuit to automatically feed material via load condition, and automatically adjust the feeding amount via the load of breaker, to realize continuous production.

Description

technical field [0001] This application relates to stone crushers. Background technique [0002] The current stone crusher consists of a crushing head and a feeding device. The crusher head and the feeding device are respectively driven by the main motor and the auxiliary motor, and the operation of the two motors is controlled manually. When the crushing head enters large stones or the feeding amount is greater than the crushing amount, the main motor will be overloaded, and finally the power will trip and stop working. At this time, the worker needs to turn off the auxiliary motor to stop feeding, and then restart it after manual removal. This kind of crusher cannot work continuously, which affects production, and manual removal of obstacles requires repeated operation of the motor, which is labor-intensive. [0003] At present, a motor overcurrent protector is commonly used in the market. This current protector is installed in the power supply circuit to protect the mot...
